And another thing. How about a code for customers. Most of mine are regulars and we all get along fine, but every now and then a bad one gets through the door. I'm sure we all have horror stories.

I propose new customers should promise to:-

Pay when the job is finished.
Not phone every 5 minutes.
Not expect free diagnosis.
Understand vehicles are complex.
Be polite.
Answer the phone.
Never patronise(my mate down the pub, read on the internet etc)

I could go on all night, feel free to add some more
